ABB identifies 3AUA0000110431 as BCU-22. ABB's BCU-02/12/22 hardware manual describes this control-unit family as controlling converters through fiber-optic links and providing integrated branching-unit functionality. The unit can collect and store real-time converter data on an SDHC memory card for fault tracing and analysis. The complete order code, installed converter type, control-unit hardware revision and current system configuration must be checked before procurement.
For the BCU-22 type, ABB specifies twelve fiber-optic connections and an external 24 V DC supply. ABB also documents three option slots for I/O extensions, encoders and fieldbus adapters, a removable memory unit, an XD2D RS-485 master/follower connection and an RDCO DDCS option-board slot. These published features support a configuration review, but they do not by themselves prove interchangeability with another BCU type or installed drive system.
